Very Bright Light with a Craft with Flashing Lights

At 10:45pm looking directly west down 49th avenue I saw a very bright light about the size of a golf ball. It looked to be about 40 degrees high and maybe a few miles away. It was so bright it had an aura of light around the outer rim. it shined in the center like crystal or glitter in spots the bottom was rounded and had 5 very small diamond shapped lights around the bottom. I turned to get my mail from the mail box and when I turned around there was the very large white light in the west and also a very large craft in the sky at approximately 49th avenue and kipling st., wheat ridgo, co. The base was a half circle with a verticle bar from the center (almost like an anchor) and looked to be about 50 to 60 feet tall and tilted 15 degrees to the north for the 1st minute and 30 degrees to the north afterward. On the verticle stem it had horizontal white lights approx 10 feet across. There were approx 15 rows of white lights from top to the base. The base was a half circle with the top 2/3 a red light and the bottom 1/3 rounded edge navy blue light. The rows of white lights would flash on all at once, the go off. Then the white lights, red and blue would all light up at once. Then the lights would go off all together. This object went from approximately 49th and kipling north to approximately 68th and ward road in arvada, colorado. I was not able to see it after that. When I looked back for the large white light in the west, it was gone. No sound heard
